Penalized classification for optimal statistical selection of markers from high-throughput genotyping: application in sheep breeds

2018

The identification of individuals’ breed of origin has several practical applications in livestock and is useful in different biological contexts such as conservation genetics, breeding and authentication of animal products. In this paper, penalized multinomial regression was applied to identify the minimum number of single nucleotide polymorphisms (SNPs) from high-throughput genotyping data for individual assignment to dairy sheep breeds reared in Sicily. The combined use of penalized multinomial regression and stability selection reduced the number of SNPs required to 48. A final validation step on an independent population was carried out obtaining 100% correctly classified individuals. …

Effects of Infant Formula With Human Milk Oligosaccharides on Growth and Morbidity: A Randomized Multicenter Trial

2017

Objectives:The aim of the study was to evaluate the effects of infant formula supplemented with 2 human milk oligosaccharides (HMOs) on infant growth, tolerance, and morbidity. Methods:Healthy infants, 0 to 14 days old, were randomized to an intact-protein, cow's milk-based infant formula (control, n=87) or the same formula with 1.0g/L 2fucosyllactose (2FL) and 0.5g/L lacto-N-neotetraose (LNnT) (test, n=88) from enrollment to 6 months; all infants received standard follow-up formula without HMOs from 6 to 12 months. Primary endpoint was weight gain through 4 months. Secondary endpoints included additional anthropometric measures, gastrointestinal tolerance, behavioral patterns, and morbidit…

Research Article <i>CD40</i> rs4810485 <i>T>G</i> polymorphism and susceptibility to ankylosing spondylitis in the Latvian…

2018

Ankylosing spondylitis (AS) is a potentially disabling form of a systemic chronic inflammatory arthritis affecting mainly the axial skeleton, with or without extraspinal manifestations. The genetic basis of AS is partly known. Moreover, many autoimmunityrelated genes have pleiotropic effects. Multiple functional polymorphisms in the genes encoding the tumor necrosis factor (TNF) superfamily of cytokines, their receptors, and signaling proteins, are associated with susceptibility to autoimmune diseases. These arguments prompted us to conduct a study evaluating a possible association of single nucleotide polymorphism (SNP) rs4810485 of the CD40 gene, found previously to be involved in other i…

INFORMACIÓN Y EXPOSICIÓN INDIRECTA PARA REDUCIR ESTEREOTIPOS HACIA EL ENVEJECIMIENTO

2016

Abstract.Purpose: The Image that society has about older people has been built on a base of stereotypes, far away from reality. This social image will have a determinant influence on attitudes and behaviors from all those people related with them, including health care professionals. It should be mandatory to eradicate negative stereotypes against aging during university formation, and in this practice get sensitive professionals who will attend people in their final state of life. Method: the treatment “Information plus indirect experience” was set throw the viewing of the short film “Como un Rolling” (Castilla, 2013). This film exposes the concept of active aging, and had the purpose to b…

Flipping of alkylated DNA damage bridges base and nucleotide excision repair

2009

Alkyltransferase-like proteins (ATLs) share functional motifs with the cancer chemotherapy target O6-alkylguanine-DNA alkyltransferase (AGT) and paradoxically protect cells from the biological effects of DNA alkylation damage, despite lacking the reactive cysteine and alkyltransferase activity of AGT. Here we determine Schizosaccharomyces pombe ATL structures without and with damaged DNA containing the endogenous lesion O6-methylguanine or cigarette-smoke-derived O6-4-(3-pyridyl)-4-oxobutylguanine. These results reveal non-enzymatic DNA nucleotide flipping plus increased DNA distortion and binding pocket size compared to AGT. Our analysis of lesion-binding site conservation identifies new A…

Abstract. Archaea are widespread and abundant in many terrestrial and aquatic environments, and are thus outside extreme environments, accounting for up to ~10% of the prokaryotes. Compared to bacteria and other microorganisms, however, very little is known about the abundance, diversity, and dispersal of archaea in the atmosphere. By means of DNA analysis and Sanger sequencing targeting the 16S rRNA (435 sequences) and amoA genes in samples of air particulate matter collected over 1 year at a continental sampling site in Germany, we obtained first insights into the seasonal dynamics of airborne archaea. The detected archaea were identified as Thaumarchaeota or Euryarchaeota, with soil Thau…

Heating glaciers from below

Climate change is affecting the cryosphere from above. Geothermal heat flux from below is also contributing to conditions at the base of Greenland's ice sheet, which sits atop a lithosphere of variable thickness.

Measuring trunk orientation with a CMOS camera: feasibility and accuracy.

2007

International audience; The purpose of this study was to develop and validate a new tool to objectively quantify trunk orientation at the bedside, especially dedicated to the measurement of the lateropulsion in acute and subacute stroke patients. We developed software to analyze 2D movement with a CMOS camera (Logitech Quickcam Pro 4000) and to calculate the orientation of a segment defined by two color markers. First, the accuracy, reproducibility and noise when measuring segment orientations were evaluated with the CMOS camera placed in different positions, and second trunk orientation was measured in static and in dynamic conditions both with a CMOS camera and with a gold standard 3D vid…

Molecular characterisation of k-casein gene in Girgentana dairy goat breed and identification of two new alleles

2015

The k-casein fraction plays an important role in the formation, stabilisation and aggregation on casein micelles and thus affects technological and nutritional properties of milk. In this study, exon 4 of k-casein (CSN3) gene was sequenced and analysed in Girgentana goat breed. Analyses of the obtained sequences showed the presence of A, B, D, and G known alleles and two new genetic variants, named D’ and N. The new D’ allele differs from D in one transition, G284→A284, which did not cause amino acid change. The new N allele differs from A in five single nucleotide polymorphisms (SNPs): T245/C245, G284/A284, G309/A309, G471/A471 and T591/C591, while it differs from C in one transition, i.e.…

Experiencing Commercial Videos for Online Shopping

2018

In recent years online shopping has become a popular and convenient instrument for companies to buy and sell products. However, the design of these web-shops does not offer the rich multisensory experiences than physical retailing offers. In the paper we argue that audio-visual contents could provide dynamic multisensory information to offer more engaging experiences to the consumer, but to achieve this goal, audio-visual contents need to be adjusted to the cultural characteristics of the users. Despite controversies regarding universalism of the emotional experiences induced by perceptual processes, we present evidence that suggests cultural modulations of videos experiences. In the report…
